JOHN E. NORDLIE, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-FOURTH TO OLE BROWN AND ONE-EIGHTH TO ORVILLE C. BROWN, OFMINNEAPOLIS, MINNESOTA.

COMBINATION -TOOL To all whom it may concern.'

Be it known that I, JOHN E. NoRDLiE, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented. certain new and useful Improvements in Combina,- tion-Tools; and Ido hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertaiiis to make and use the saine.

My invention has for its ob]- ect to provide an improved combination square, bevel square and gage, and to this end it consists of the novel devices and combinations of devices hereinafter described and dened in the claims.

In the accompanying drawings, which.

illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1is a View chiefly in side elevation, but with some parts broken away and with some parts sec# toned, showing the improved tool; Fig. 2 is a section taken on theliiie m2 x2 of Fig. 1; Fig. 3 is a detailed View showing the plunger of the tool and certain parts mounted thereon` removed from working position; Fig. 4.is an enlarged section taken` on the line m4 x4 of Fig. 3; and Fig. 5 is an enlarged section taken on the line mi m5 of Fig. 3.

The head 1 of the square is lpreferably a.

casting which is forinedwith a true' longitudinally extended working edge 2 and, at one end, with a bevel surface 3 that extends at an angle of 45O to the said straight edge'2. The back portion of the head1 is formed with a longitudinally extended seat 'in which a' plunger or sliding bolt 4 is mounted for endwise movements only. This plunger 4 is formed with a groove 5 that preferably eX- tends from end to end thereof.

At one corner of the head 4 a flat graduated blade 6 is pivotally connected by a screw 7. The head 2 lis provided with a deep slot 1a that extends fromy end to end thereof and within which the blade 6 is mounted to work. Said blade, at'its inner end, isprovided'with a segmental portion S that remains always within the deep slot 1a of the head 1l and a portion thereof-Vis always within the groove 5 of the 'plunger 4,

so lthat the latter is-thereby held against ro` Specification of Letters Patent.

tation but is, nevertheless, free for endwise sliding movements. The segmental portion 8 of the blade 6 has a multiplicity of closely positioned holes 9 that are adapted to be engaged` by the curved lock finger 10 of a lock sleeve 11 mounted on the plunger 4 and lo cated within a suitable seat provided therefor in the head 1. The main body portion of the lock Vsleeve 11 is threaded, but from its threadedportion toward its outer end, towit, its Vri'ghthand end, as shown in Figs. 1 and 2, it is. out away at 11a so that it will clear the segmental portion 8 of the blade 6.

The numeral 12 indicates a threaded plug which is screwed into thevpivot end of the head 1. y This plug 12 is slit or cut through at 12@L to aord clearance for the segmental portionS of the said blade 6.

At its back, the head 1 is provided with three notches 13, 14 and 15. Mounted on the plunger 4, and located within the notch 13, is a camacting lock sleeve 16 that is providedV an internal cam lug 17 that cooperates with a reduced eccentric cam surface 18 of the said plunger 4. This cam surface 1S extends from one side of the groove 5 a short distance circumferentially of the plunger 18. Normally, the cam lug `17 isl withiiiithe groove -5 and the plunger 4 is then free for endwise movements. When, however, the lock sleeve 16 is oscillated so as to force the cam lug 17 on to the cam surface 18, the said plunger will be frictionally locked against endwise movement. At its right hand progecting end, the plunger 4 is ,provided with a sharp tooth 19 which serves as the marking orscratching device of the gage when the adjacent end of the head 1 is `placed against a board or other object and ldrawn over the same.

The lock sleeve 16, therefore,l affords means for locking the plunger 4 with this tooth 19 secured at any desired distance away from the adjacent end of the head 1. g

Located within the notch 14, and loosely surrounding the threads of the threaded portion 'of the lockvsleeve 11, is a threadloss collar 20 that is provided with a key lug 21 that engages a longitudinal slot 20 formed in lthe threaded portion of the lock sleeve 11. By means of this collar 20, the lock. sleeve 13 may be voscillated so as to throw its lock `finger 10 into or out of engagement with any one of the holes 9 in the segmental portion 8 ofthe blade-6. As is evident, the blade 6 may be locked in approximately any desired angular' position in respect to the str ight edge2 of the head l, by engagement of the lock finger l0 with one of the holes 9. IVhen this is done, the final and very accurate setting of the blade 6 may be accomplished byv endwise movement of the so F called lock sleeve l1, which movement is effected by an annular nut 22 which is located in the notch 15 and works with threaded engagement on the threaded portion of said lock sleeve 1l. To secure the lock sleeve 1l either in its operative or inoperative position, an annular lock nut 23 is mounted on a reduced threaded portion of the operating` collar 20. IVhen this lock nut 23' is screwed away from the shoulder of the collar 20, it will press against one extremity of the slot 14 and will force the other end of saidcollar 20 against the other extremity of said notch Hand thereby lock the said collar and, consequent-ly, the lock sleeve ll against rotation. j

' At its pivoted end, the blade G is preferably graded in degrees, as indicated at 24, to indicate the angle position thereof in respectto the straight edge 2 of the head l.

This improved tool, while capable of very general use, hasbeen especially designed for use by carpenters and builders andV is particularly adapted for use in the framing of buildings, in the laying out of stairs, cutting of rafters, joists. and other parts of a house.

1When the blade G is turned into its folded position, as shown by dotted lines in Fig. l, it is capable of being carried in a pocket or l being packed within very small space.

The segmental portion 8 of the blade G might have notches in lieu of the perforations 9, but this would be the equivalent of the said perforations.

The beveled end surface 3 of the head l is useful in laying out certain kinds of work at an oblique angle when the blade 6 is set at a right angle to the straight edge 2 of the said head.

lVhat I claim is:
